( Fig. 23)

ZooBank LSID: urn:lsid:zoobank.org:act: Type species: Litoria mucro ( Menzies, 1993) .

Content: Five species— Nasutibatrachus mareku ( Günther, 2008) comb. nov., Nasutibatrachus mucro * ( Menzies, 1993) comb. nov., Nasutibatrachus pinocchio (Oliver et al., 2019) comb. nov., Nasutibatrachus pronimius * ( Menzies, 1993) comb. nov.,

Nasutibatrachus vivissimia* ( Oliver, Richards & Donnellan, 2019) comb. nov.

Diagnosis: Nasutibatrachus can be diagnosed from members of the Drymomantis Sub-clade except Exochohyla and Teretistes , by the presence of a rostral spike. It can be diagnosed from Exochohyla by the absence of the rostral spike in females vs. presence in both genders, short vs. medium mean call duration; from Teretistes by reduced vs. no finger webbing and reduced vs. minimal toe webbing. Refer to Tables 1 and 2.

Distribution and ecology: New Guinea mainland, near sea level up to at least 2200 m a.s.l. Arboreal frogs that breed in ponds and ditches but eggs and tadpoles unknown. Males call from foliage adjacent to lentic waterbodies in forest.

Etymology: From the adjectival form of the Latin nasus (nose) and the Greek βάτΡαΧος ( batrachos, frog), alluding to the rostral projection. As with other generic names based on batrachus, the gender is masculine.

Remarks: Menzies (2006) considered havina, mucro , and pronimia to belong to the Litoria (= Kallistobatrachus ) iris group. Description of the tadpole of K. pronimia by Menzies may refer to Teretistes havina . Genetic data are unavailable for Nasutibatrachus mareku and N. pinocchio but these are small, slender species in which the male has a rostral spike and Oliver et al. (2019) placed them in a phenetic group containing both N. mucro and N. pronimia .
